The dietary supplement of Ginkgo biloba: a comprehensive review of its potential interactions based on pre-clinical and clinical evidences / El suplemento dietético de Ginkgo biloba: una revisión exhaustiva de sus posibles interacciones basada en evidencias clínicas y preclínicas

This review present Gingko biloba (GB) interactions, based on clinical and pre-clinical presentations. Literature was retrieved using databases; ScienceDirect, PubMed, Google scholar, Web of Science, Scopus etc. 14/45 interactions were found with clinical presentations. More interactions (80%) were reported with drugs followed by herbs (11.1%), and nutraceuticals (6.7%) with major mechanisms of interaction observed as; inhibition of Cytochrome metabolizing enzymes (44.4%) and platelet-activating factor (PAF) i.e. 15.6%. Major clinical features were; increased bleeding (eye, parietal), hematomas (subdural), and seizures as well as increased blood pressure, priapism, loss of infection/antiviral failure, and coma. Drugs with major interactions belonged to anti-platelet/anti-coagulant and NSAIDs. Synergistic effects were observed for GB vs herbs (except cannabis which showed rhabdomyolysis), foods, and nutraceuticals (except pyridoxine where neurotoxicity was seen). GB use should be monitored and the patient may seek proper advice from a healthcare professional.

Esta revisión presenta las interacciones de Gingko biloba (GB), basadas en presentaciones clínicas y preclínicas. La literatura se recuperó utilizando bases de datos; ScienceDirect, PubMed, Google Scholar, Web of Science, Scopus, etc. Se encontraron 14/45 interacciones con presentaciones clínicas. Se informaron más interacciones (80%) con fármacos seguidos de hierbas (11,1%) y nutracéuticos (6,7%) con los principales mecanismos de interacción observados como; inhibición de las enzimas metabolizadoras del citocromo (44,4%) y factor activador de plaquetas (PAF), es decir, 15,6%. Las principales características clínicas fueron; aumento de sangrado (ojo, parietal), hematomas (subdural) y convulsiones, así como aumento de la presión arterial, priapismo, pérdida de infección / insuficiencia antiviral y coma. Los fármacos con interacciones importantes pertenecían a los antiplaquetarios/anticoagulantes y los AINE. Se observaron efectos sinérgicos para GB frente a hierbas (excepto cannabis que mostró rabdomiólisis), alimentos y nutracéuticos (excepto piridoxina donde se observó neurotoxicidad). Se debe controlar el uso de GB y el paciente puede buscar el asesoramiento adecuado de un profesional de la salud.

Ganoderma lucidum (Reishi) an edible mushroom; a comprehensive and critical review of its nutritional, cosmeceutical, mycochemical, pharmacological, clinical, and toxicological properties.

Reishi owes an exceptional value in nutritional, cosmeceutical, and medical treatments; however, none of the studies has provided its future-driven critical assessment. This study documents an up-to-date review (2015-2020, wherever applicable) and provide valuable insights (preclinical and clinical evidence-based) with comprehensive and critical assessments. Various databases 'Google scholar', 'Web of Science', 'ScienceDirect', 'PubMed', 'Springer Link', books, theses, and library resources were used. The taxonomic chaos of G. lucidum and its related species was discussed in detail with solution-oriented emphasis. Reishi contains polysaccharides (α/ß-D-glucans), alkaloids, triterpenoids (ganoderic acids, ganoderenic acids, ganoderol, ganoderiol, lucidenic acids), sterols/ergosterol, proteins (LZ-8, LZ-9), nucleosides (adenosine, inosine, uridine), and nucleotides (guanine, adenine). Some active drugs are explored at an optimum level to make them potential drug candidates. The pharmacological potential was observed in diabetes, inflammation, epilepsy, neurodegeneration, cancer, anxiety, sedation, cardiac diseases, depression, hepatic diseases, and immune disorders; however, most of the studies are preclinical with a number of drawbacks. In particular, quality clinical data are intensely needed to support pharmacological activities for human use. The presence of numerous micro-, macro, and trace elements imparts an essential nutritional and cosmeceutical value to Reishi, and various marketed products are available already, but the clinical studies regarding safety and efficacy, interactions with foods/drinks, chronic use, teratogenicity, mutagenicity, and genotoxicity are missing for Reishi. Reishi possesses many valuable pharmacological activities, and the number of patents and clinical trials is increasing for Reishi. Yet, a gap in research exists for Reishi, which is discussed in detail in the forthcoming sections.

Evaluation of solvent and temperature effect on green accelerated solvent extraction (ASE) and UHPLC quantification of phenolics in fresh olive fruit (Olea europaea).

A green ASE (accelerated solvent extraction) with a shorter UHPLC (ultra-high performance liquid chromatography) method was developed for simultaneous determination of phenolics. High extract yield (130 mg/g) was observed for water at 100 °C in a short time of 19.5 min using 33.5 mL solvent whereas, UHPLC showed more phenolics of GA (gallic acid), QT (quercetin), LT (luteolin) in ACE (acetone) and RT (rutin) in EtOH (ethanol) solvent at 60 °C. The binary solvent system of ACE: EtOH (1:1) at 60 °C was optimized as extraction set. UHPLC runtime was 3 min with retention times of (min); 0.63 (GA), 0.97 (RT), 2.00 (QT) and 2.41 (LT). Average for phenolics (ppm) was, QT (10.91) > GA (7.33) > LT (4.10) > RT (3.90) whereas, Spanish whole green olive (SP2) showed more phenolics (20.72). Individual phenolic was, GA (47.06) > RT (26.21) > QT (19.34) > LT (6.18). Multivariate, K-mean and PCA (principal component analysis) for solvent*extract yield showed significant correlation and temperature showed no significant correlation for phenolics.
